I also got this book for Christmas and agree it is full of good information. I too, was most intrigued by the monocular/binocular vision breakdown. I ride trails, and my horses will instinctively stop when they hear/see something approaching, and it does take a few seconds (long after I am saying, just a guy walking...) for them to get it completely in focus, size it up, and understand that there is no threat present. Then I can move them along. I let them do this even more willingly, rather than pushing them through immediately, after understanding their vision.
